INFORMATION ABOUT THE PORT
The Port is a municipal corporation of the State of Washington (the state), organized on
September 5, 1911, through enabling legislation by consent of the voters within the Port district.
In 1942, the local governments in King County, Washington (the County) selected the Port to
operate the Seattle-Tacoma International Airport (the Airport). The Port is considered a special
purpose government with a separately elected commission of five members. The Port is legally
separate and fiscally independent of other state or local governments. All revenues and receipts
must be disbursed in accordance with provisions of various statutes, applicable grants, and
agreements with the holders of the Port’s bonds.
The Port and its Enterprise Fund, which is used to account for operations and activities that are
financed at least in part by fees or charges to external users, is comprised of three operating
divisions. The Aviation Division manages the Airport serving the predominant air travel needs of
a five-county area. The Maritime Division manages industrial property connected with maritime
businesses, recreational marinas, Fishermen’s Terminal, cruise, grain and maritime operations.
The Economic Development Division focuses on managing the Port’s industrial and commercial
properties including conference and event centers, encouraging tourism, developing small business
opportunities, and providing for workforce development in the aviation, maritime and construction
industries.
For 2017, the Port had total operating revenues of $632 million, which represents a 5.6 percent
increase from 2016. Total operating expenses increased from $325.3 million in 2016 to $373.0
million in 2017. The Port’s net operating income before depreciation decreased $14.1 million
from 2016 to 2017.
